이렇게 장비 접속까지는 완료 하였습니다.
디폴트 Hostname를 FW01변경 하겠습니다.

Site to SIte VPN를 테스트 하기 위해서 기본 설정을 다 하였습니다.
FW01에서 VPN -> IPsec Wizard
Name: S2S VPN
그리고 next를 클릭 합니다.
Remote IP: 192.168.100.2 -> 상대방 WAN IP주소 입니다. 이 주소는 서로간에 Ping이 가능해야지 IPsec vpn연결이 가능 합니다.
Outgoing Interface: WAN(port1)
Pre-sahre Key: CiscoCisco
그리고 next를 선택 합니다.
Local Subnet:
172.17.70.0/24
172.17.71.0/24
172.17.72.0/24
172.17.73.0/24
Remote Subnet
10.1.1.0/24
Interface access: None를 설정합니다. 이유는 위에 IP대역에 대해서만 IPsec VPN 터널를 타고 마너지 트래픽은 로컬 ISP01인터넷을 사용합니다.
아래 정보를 확인하고 Create를 클릭 합니다.
아래처럼 S2S VPN 터널이 자동으로 생성 되었습니다.
FW02도 똑같이 설정 합니다.
Remote IP: FW01 WAN에 IP를 입력합니다.
outging interface: WAN(port1)
Pre-shared Key: CiscoCisco
Local Subnet: 10.1.1.0/24
Remote Subnet: 172.17.70.0/24
172.17.71.0/24
172.17.72.0/24
172.17.73.0/24
아래 정보값을 확인후 맞으면 Create버튼을 클릭 합니다.
터널을 확인합니다.
현재 Traffic이 없기 때문에 터널이 Down 입니다.
Traffic를 발생해 보겠습니다.
방화벽에서 자체적으로 Tunnel쪽으로 Traffic를 발생 시켜서 Tunnel를 강제로 UP를 유지 할수 있습니다.
아래 처럼 auto-negotiate를 선택하면 자동으로 Autokey keep alive도 선택 됩니다.
FW02도 똑같이 설정합니다.
그리고 터널 인터페이스를 확인 합니다.
터널이 UP되었습니다.
SW01에서 SW02로 Ping시도

이렇게 Site to Site VPN를 통해서 서로 ping이 가능 합니다.
이번에는 VPC 4생성하고 아래와 같이 연결 합니다.

이렇게 두개 지점에 Fortigate 방화벽에 Site to Site VPN를 이용해서 통신 하는 방법에 대해서 알아보았습니다.
다음장에서는 Wizard를 이용해서 Site to Site VPN를 설정했을떄 어떤부분이 자동으로 생성이 되는지 확인해보겠습니다.
지금까지 글을 읽어주셔서 감사합니다.
